    Answer:  0.1587

    Step-by-step explanation:

    Given : The amount dispensed is approximately normally distributed with Mean : \mu=\ 16

    Standard deviation : \sigma= 1

    The formula to calculate the z-score :-

    z=\dfrac{x-\mu}{\sigma}

    For x= 17

    z=\dfrac{17-16}{1}=1

    The p-value = P(17<x)=P(1<z)

    =1-P(z<1)=1-0.8413447\\\\=0.1586553\approx0.1587

    The proportion of bottles will have more than 17 ounces = 0.1587
